Hi guys, i am using ubuntu 20.04 i added a superuser and i get the error: Code: tom@tom-Macmini:~$ ssh [email protected] [email protected]: Permission denied (publickey). when i login as root there is no problem, only with the user tomdf is a problem. I deleted the rsa key and generate it new but i have still the same problem. maybe you have any idea thanks a lot for your help
Have you set up passwordless login with ssh keys? Since ssh command does not ask for password, my guess is you have login with password disabled (this may be the default for superusers).
